Read spaces in String as Input Without using NextLine

Question

Discription:

I used several scanner statments in below code. First i Read the "Adress" and then "Mobile No." and then some random stuff from user.

When i use adress=sc.next()

it reads the string value of adress from user(Without space) and go to the Next scan statement i.e. mobile=sc.nextBigInteger(). by using this method i am not able read the spaces in "adress(string) " and it throws the runtime error as inputMismatchException.

Now if i use the adress=sc.NextLine, the Progrram directly jumps to the mobile=sc.nextBigInteger().

How is it possible to read the spaces as input in above situations and the below code. How can i protect myself from runtime Errors. I got similar questions on the forum but non of them was satisfactory. Thank you. (Ask me if you need more information about question)

Expected: input(In adress string) : pune maharashtra india

output(in display function) : pune mahrashtra india.

What exactly happened: if input(in adress string) : pune output(in display function) : pune

if input(in adress string) : Pune india
(Now As soon as i entered the string and hit the enter there I get a runtime error as an inputmismatchexception )

           AcNo = sc.nextBigInteger();

           System.out.println("Enter the IFSC Code");
           ifsc= sc.next();
        }

           public static void main(String[] args) {
               Data d=new Data();

Answer 1

Change this line ;

adress= sc.next();

with this line ;

adress = sc.nextLine();

this will solve your problem. scan.nextLine() returns everything up until the next new line delimiter, or \n ,but scan.next() is not.

So all code will be like this ;

public class Data{

    String adress;
    BigInteger AcNo;
    BigInteger mobile;
    String ifsc;

    void getData() {

        System.out.println("Welcome to  Bank System");

        System.out.println("Please Enter the adress :");
        adress = new Scanner(System.in).nextLine();

        System.out.println("Enter the Mobile Number");
        mobile = new Scanner(System.in).nextBigInteger();

        System.out.println("Enter the Account Number");
        AcNo = new Scanner(System.in).nextBigInteger();

        System.out.println("Enter the IFSC Code");
        ifsc = new Scanner(System.in).next();
    }

    public static void main(String[] args) {
        Data d = new Data();
        d.getData();
    }
}
